Side-chain Interactions

Select up to 10 residues for interaction analysis

Proximity threshold 5Å

How to use: 1) Set the proximity threshold (Å). 2) Select a side chain — nearby residues within the threshold will be highlighted blue. 3) If any nearby residues have predicted chemical interactions with your selection they will be highlighted green. Select interacting residues and click Analyze to see details.
